Add an explicit note pointing out that sched_process_exit tracepoint is,

sync (though, on the best effort basis).

This is a follow-up to [0], and can hopefully be just folded in when applying.

Thanks, I've folded this into the tracepoint patch, with this small edit:

 s/sched_process_exits
  /sched_process_exit
